Best Buy's (BBY-1%) pledge to match the prices of online rivals is limited to a case-by-case basis with some sales associates empowered to hash out price breaks with customers on the spot. The matching prices will only apply to 20 online sellers, headed up by behemoth Amazon as well as pure Internet plays Newegg.com and Buy.com.

I can see it now. Loud negotiations on the floor with customers asking for the manager. Other customers being neglected. All the while prices on amazon changing frequently (as they sometimes do all day long) to "catch the wave"!
